Famous Poems Life Death

poems or quotes about life/death..happiness..?

My brothers friend, thats a girl, but not a girlfriend, recently passed away. he was close to her and this really upset him (obviously). but anyways he wants to get in to the music industry so im making him a gift and its going to be dedicated to her, does anybody know any famous poems or quotes or anythiung nice to say in the dedication, its not like suicide so nothing dark or anything, but you know maybe a poem or quote about being missed or im glad i met you and you changed my life, or never forgetting her, or something special.

any ideas?

“The angels, not half so happy in heaven,
Went envying her and me-
Yes!- that was the reason (as all men know,
In this kingdom by the sea)
That the wind came out of the cloud by night,
Chilling and killing my Annabel Lee.
For the moon never beams without bringing me dreams
Of the beautiful Annabel Lee;
And the stars never rise but I feel the bright eyes
Of the beautiful Annabel Lee;”

This is a poem of edgar Allen Poe “Annabel Lee” the entire poem is a lament of a man that lost his young bride but the entire poem is strangely upbeat for such a dreary topic. The poem also always alludes to them meeting agian and that their love goes on forever.
